" Every Red Bull Air Race is a struggle\u2014not just among competitors, but between pilots and the course. For June&amp;#039;s championship, the first to be flown in New York City, race director Jim DiMatteo crafted a high-g&amp;#039;s course along the Hudson River near the Statue of Liberty. DiMatteo&amp;#039;s team calculates the planes&amp;#039; speeds, turn rates and turn radii to ensure the pilots are not exposed to g-force spikes greater than 12. They also use simulations to ensure spectators won&amp;#039;t be hurt by debris in the event of a crash. As in downhill skiing, the act of turning slows the racers. &amp;quot;We never pull the throttle back,&amp;quot; pilot Kirby Chambliss says. Racers push the track&amp;#039;s limits by taking smart, risky turns. &amp;quot;Pilots who win don&amp;#039;t go through the gates straight,&amp;quot; Chambliss says. &amp;quot;I&amp;#039;m going through them at a crazy angle.&amp;quot;   1. Pilots approach the track&amp;#039;s first gate at 230 mph. The gates are attached to barges that shift with the wind and tide. &amp;quot;It&amp;#039;s like racing a car on a street that keeps moving beneath you,&amp;quot; Chambliss says. 2. Pilots move an airplane&amp;#039;s nose as little as possible as they slalom, cutting angles so closely that their wingtip vortices nudge the inflatable gates. 3. This bend will produce at least 4.3 g&amp;#039;s in cockpits; pilots may experience spikes above 10 g&amp;#039;s. &amp;quot;Anything above 4.0 is training and tolerance,&amp;quot; pilot Mike Goulian says. 4. Pilots snap their rides on their sides, called knife flying, to steer through Gate 4 in a vertical position. Cameras ensure the turn is performed within a 20-degree standard. 5. The turning maneuver at Gate 7 is a chance for pilots to re-establish a strategy for the return trip through the course. Pilots typically climb and roll their airplanes to gain a better angle on the gates.      "^^<http://www.w3.org/2001/XMLSchema#string>
